Alternative solution and strength check of mechanical screens
Sommer, Matěj ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master’s thesis deals with a new design of bar screens. The goal was to come up with an alternative design to already existing device by INKOS a. s. In the first part, there is a summary of various machines working in similiar conditions. The insights gained by this research influenced the design of the new device. It utilizes well proven solutions from previous projects, but some of these were reworked and a few new functions were added. Second part of the thesis describes the analytical solutions, which were used to determine the forces in the assembly during the operation of the device. Based on the results of these calculations, a strength analysis of important components was performed using the finite element method. The result of this thesis is the design and optimization of new bar screens, including engineering drawings and tools for its further development.

Anaerobic digestion of sludge from pulp and fodder yeast production
Řezáč, Jaroslav ; Beňo, Zdeněk (referee) ; Pěček, Jan (advisor)
The thesis aims to identify suitable and in the locality available raw materials to a commnon fermentation with sludge from pulp and fodder yeast production in company Biocel Paskov a.s.. Introductory chapter briefly describes the mechanisms of penetration of the sludge itself. The following section deals with origin, chemical composition and properties of biogas. The factors affecting the production of biogas are described. A key part of this thesis is a performance of sludge fermentation test and selected mixed substrate. Acquired knowledge is evaluated and the optimum composition of input raw materials with regard to maximum, but also economic recovery of biogas selected. Further, on the basis of obtained data a rough draft of biogas station is done, icluding its energeic and economic balance.

Heat balance of anaerobic part of sewage treatment plants
Řezáč, Jaroslav ; Beňo, Zdeněk (referee) ; Pěček, Jan (advisor)
This thesis is focused on anaerobic stabilisation of sewage produced by sewage treatment plant. Mesophilic stabilisation was chosen for the sewage treatment plant . In the first chapter, main attention is dedicated to general treatise on sewage treatment plant. Anaerobic process of stabilisation, digestion tank and some of the medium are characterised there. Next chapter is dealing with thermal balance for selected version of sewage stabilisation. A proposal of digestion tank and thermal insulation is also made there. Further, heat exchanger, boiler and combined heat and power unit are projected.

Development of local roads in Přibyslavice
Dušek, Martin ; Halodová, Klára (referee) ; Všetečka, Martin (advisor)
The aim of the diploma thesis is to help the town of Přibyslavice with the development of local communications. This includes project work based on the current needs of the town and related consultations with local representatives and building authority. First, a passportization of local communications was drawn and subsequently, widening of the communication network by three new roads was suggested. This will enable creation of new building plots. New sewage and rainwater drainage, together with water conduit, were designed. Emphasis was put on avoiding interference with plots not owned by the town, on comfortable access to currently used plots, safe connection to the existing regional road no. III/3798, and sufficient radius for passage of firefighters and a garbage truck.

Familly House
Pourová, Veronika ; Blažek, Petr (referee) ; Čuprová, Danuše (advisor)
The theme of bachelor´s thesis is family house in Miletin. The family house is a single unit building intended for the permanent family living. It is a family house with two floors and basement. Family house is set in a slinty sloping terrain. The building was constructed using traditional materials and technologies. The building is designed of system POROTHERM and ceiling construction of system POROTHERM MIAKO. The cladding is insulated by contact insulation. Facades are broken color in combination with a large glass window openings. The windows are plastic with insulating glass. The roofs are flat.

Study of variants of sewerage in the village Vír
Macík, Ondřej ; Macsek, Tomáš (referee) ; Hluštík, Petr (advisor)
Most of the municipalities in Czech republic have old or even disfunctional sewage systems for built up communal areas. General combined sewage systems built earlier are being today replaced by solutions separating rain waters and sewage waters. Municipality Vír has currently only few sewage branches that consequently flow into Svratka river. Aim of this Diploma Thesis is to propose 3 solutions for sewage produced in communal areas of Vír municipality and its consequent disposal in sewage treatment plant. Each of three solutions feature combined gravity-driven and pressure systems of sewage lines as well as water treatment in proposed MTB as well as household and container WTP. Each of three variant is economically weighed with proposed budget.
